WINDMILL.

SPECIFICATION forming part of Letters Patent No. 677,805, dated July 2 1901. Application filed October-ll, 1900. Serial No. 32,762. (No model.)

Be'it known that I, ALBERT TITIAN Soon, a citizen of the United States, residing at Defiance, in the county of Shelby andState of Iowa, have invented certain new and useful. Improvements in Windmills; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as it appertains to make and use the same.

This invention relates to the general conare strengthened, braced, and rendered more positive and smooth in operation.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of is to be had. to the following description-and drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in whiclr.

Figure 1 is a detail view of the adjunctivo parts of a windmill,such as the regulator, the governor, the pump, and the tower. Fig. 2 is a detail plan view ofthe bed of the governor mechanism, showing the valve and controlling mechanism therefor, the said bed and the valve-operated lever having an intermediate portion broken away. Fig. 3 is a detail view in elevation of the governor, parts being in section and the float having an intermediate portion broken away. Fig. 4is a detail View in elevation of the pump and the 5 is a vertical central section of the float and the parts directly connected therewith. Fig. 6 is a View of the float inverted. Fig. 7 is a horizontal section of the pump-head and attached parts about on the line X X of Fig. 4. Fig. 8 is a detail view in perspective of the pump-head, showing some of the braces connected thereto.

Corresponding and like parts are referred to in the followingv description and indicated in all the views of the drawings by the same reference characters. I

The tower or derrick 1' may be of any desired form of construction and is of the usual wind-engine, the pump-rod 3 extending to the positively-actuated part of the windmill.

(Not shown.) The regulator 4 for throwing the windmill out of gear is of the hydraulic type and may be of any construction.

of the regulator connected therewith by the chain 6, is mounted so as to return the said movable part to a normal position after being'actuated and is connected with thereleasing chain or line 7 in any selected way. The governor 8, located in the tank 9, cooperates with the pipe 10, bymeans of which the water is supplied from the pump to the tank, and the mechanism of the governor is substantially the same as that set forth in Patent No. 645,019, granted me Marcht, 1900. NVithin the spirit of the present invention the foregoing-enumerated parts may The 1 weighted "lever 5, having the movable part.

be of any make or variety so long as they operate in the ordinary manner to maintain a predetermined level of the water in the tank and to throw the windmill into and out of gear at the proper time, so as to prevent overflow of the tank or the emptying thereof.

It. has been found in practice that the pump soon becomes loosened from the platform or other support by reason of the upward thrust and jar of the pump-rod, and inconvenience and annoyance result in tightening and replacing the fastenings employed for holding the pump in place. In accordance with this invention the pump is braced vertically and laterally from above by means of bars or rods 11, which are attached at their lower ends to the upper plate 12 of the pump-head 13 and have their upper ends firmly secured to'the corner-posts or other convenient part of the tower or derrick. The braces 11 being upwardlydivergent likewise serve to stiffen and stay the parts of the tower, as well as hold the pump in position against Vertical and lateral displacement. In order that the pumphead 13 may be enabled to sustain the strain to which it is subjected, it is composed of vertical standards 14, connected at their lower ends to a plate 15 and at their upper ends to the plate 12, and these standards are trans- The bed or base 18, supporting the valve and governor mechanism, is of skeleton form and approximately of diamond shape, as shown most clearly in Fig. 2, and is secured to the bottom of the tank 9 in any substantial manner. The'valve-seat 19 is formed with or [applied to one end of the bed 18, and the valve 20 is connected to an offstanding portion thereof in such amanner as to squarely seat itself under varying conditions, thereby completely shutting off the inflow'of waterv into the tank when the predetermined level has been reached. The valve-operating lever 21 has connection with the head 22, at thelower end of the vertically-movable tube 23,-

by means of a rod or bar 24 instead of a chain or like flexible connection, asshown in my previous patent herein referred to. As a result of the rigid connection 24 between the parts 21 and 23 the said lever 21 is positively actuated upon the descent of the float,,thereby permitting the valve 20 to open quickly when the level of the water in the tank 9 recedes below the minimum level. The weighted lever 25 for holding the valve-operating lever 21 elevated at its free end is provided at its upper end with transversely-spaced arms 26, which are connected by rods 27 with the collar or stop 28 and slidably mounted upon the lower end portion of the tube 23. When the float 29 descends and is approaching the limit of its downward movement, itcomes in contact with the collar 28 and depresses it and effects a release of the lever 21 from the lever 25, and should the said lever 21 stick or refuse to operate the weight of the float coming upon the head 22 will cause the outer end of the said lever 21 to move downward by reason of the force .transmittedthrough the rods 24 to the outer end of the lever 21-, as will be readily comprehended. The collar 28 has a limited downward movement prior to coming in contact with the head 22, thereby permitting the release of the lever 21 prior to the downward movement of the tube 23. The guide-rod 30, by means'of which the float 29 is directed in its vertical movements, is secured at its lower end to the end of the bed '18 opposite the valve-seat 19 and is stayed by braces 31, attached at their lower ends to the bed 18 and having their upper ends made'fast to the bracket 32, clamped or' otherwise secured to the rod 30 at a point between its ends. The float 29 is hollow and closed at its top and sides, the bottom or lower end being 13y having the float hollow and its lower end openair'eonfined-thereiir is adapted to be compressed, so that the action of the float while positive is'notsudden, and the tube 23 can be moved either up or down by a force equal to the amountof water displaced plus the force resulting. from the compression of the air in the upper portion of the float. This construction-has been'found in practice to give the best results, and for this reason is preferred. l

, The operationof the different parts is not different materially from th'ecorresponding mechanisms of windmill apparatus. Hence a detailed descriptionis not deemed necessary,

especially since any type of hydraulic regulator andgoverning mechanism may be substituted for those shown and described.

Having thus described the invention, what is claimed as new is' 1. In a windmill,the combination with the valve mechanism for controlling the flow of water into the tank, and a float-controlled support having rigid connection with the valve-controlling-lever, of a detent mechanism for holding the free end of the valve-controlling lever elevated, and a stop in the path of thefioat to release the detent mechanism priorto the actuation of the float-controlled support by the descent of the float, substantially as described.
